| Abstract: | Analyzing the measurement uncertainty of natural gas flowrate is important. However,some marked influential factors are usually ignored during actual measurement of natural gas flowrate, which results in the reduction of the fiduciary level of analysis or calculation. In this paper the current method to solve this problem with example is presented,and meanwhile,some influential factors for concern parameters are also put forward and analyzed. |
